Windows 8 Booting (IGPU works, PCI-E GTX750Ti doesn't work

Hi guys,

I have a problem and I've tried to figure it out for the whole day now.

It's mind-boggling and SUPER frustrating at the same time.

Basically I installed a fresh copy of Windows 8.1 Pro to my computer and when I plug both DVI cables into the GTX 750Ti (I run Dual monitors) it goes to the 'Windows 8 Blue logo start up but then suddenly my monitors have no signal (and my mouse turns off, aka it looks like my USB shutsdown) but my mobo is still on + cpu fans/case fans, etc.

So I tried using the IGPU and it works fine, you can plug one DVI into the IGPU DVI out, and one monitor DVI to the GTX750Ti and it will boot into windows fine.

The biggest thing that boggles me is that upon a fresh install it worked fine, AND I can reinstall windows fine again, but it *SEEMS* like after I install the NVIDIA graphics card drivers it starts happening again and I can only use IGPU to boot into windows. Now, when I first installed windows it was working fine, till I shut it down and it won't boot again hence having to try IGPU. I tried formatting, I've tried everything!

All my parts are brand new, I've tried everything there is to try, and googled alot (I've enabled/disabled secureboot multiple times, I've done 'primary display adapter 'PCI-E' and switched between them), I've tried almost everything!

My specs are as follows:

ASUS Geforce GTX750Ti GPU
Asrock H97M-ITX/ac MOBO
RAM: Corsair Vengeance 8gb
Samsung EVO 840 SSD

I've fiddled around with all the Asrock bios settings to no avail.

Someone help me PLZ!!!! As I need my computer for the week

The craziest thing is - Sometimes it works sometimes it doesn't - remember it goes to blue windows 8 logo AND THEN there is no monitor signal.


If I use Integrated Graphics it 100% always works. I'm thinking it might be some sort of bios problem maybe? I really don't know anymore :|

Which slot do you have the card in, the one closest to the processor?

Have you checked the paperwork on the GTX to see if there are restrictions on which outputs can be used as the same time?

Are the monitors matched?

I will have to research on having the onboard and discreet video outputs operational at the same time. I believe on mine, the system will disable one or the other. You might check your bios settings to see what options are available for that configuration.
